Abstract
The incidence of haemophilic arthropathy in multiple joints decreased due to treatment with clotting factor. Nowadays patients are enabled to live a rather normal life, resulting in more (sports) trauma-induced arthropathy in isolated joints like the ankle. As surgical treatment options, fusion of the tibiotalar joint and total ankle replacement are available. Both standard treatments have complications and therefore an alternative treatment is desired. In this study, treatment of haemophilic ankle arthropathy with joint distraction was explored. Three patients with haemophilic ankle arthropathy were treated with joint distraction using an Ilizarov external fixator. Clinical outcomes like function, participation and pain were evaluated in retrospect with three different questionnaires: haemophilia activities list, impact on participation and autonomy and the Van Valburg questionnaire. Structural changes were assessed blinded on X-ray by the Pettersson score and ankle images digital analysis (AIDA) and by an MRI score. All three patients were very satisfied with the clinical outcome of the procedure. They reported a clear improvement for self-perceived functional health, participation in society and autonomy and pain. Partial ankle joint mobility was preserved in the three patients. The Pettersson score remained the same in one patient and slightly improved in the two other patients, while joint space width measured by AIDA and the MRI score demonstrated improvement for all three patients after ankle distraction. This study suggests that joint distraction is a promising treatment for individual cases of haemophilic ankle arthropathy, without additional risk of bleedings during treatment.
